WP Rocket + Imagify: The Power Duo for WordPress Speed
WP Rocket and Imagify are made by the same team, so they complement each other perfectly.
WP Rocket (performance & caching)
- Page caching for instant loading
- Minify/Combine CSS & JS
- Lazy-load for images/videos
- Database cleanup
- Preload cache for Google
Imagify (image optimization)
- Compresses images automatically
- Bulk optimization for existing media
- Converts to WebP format
- Keeps quality high, but file size low
Why together?
WP Rocket reduces how content is delivered.
Imagify reduces how heavy that content is.
Together = maximum speed boost with minimal effort.
Hostinger Business Hosting: The Foundation
Even the best plugins can’t fix slow servers. Hosting matters.
That’s why I use Hostinger Business Hosting:
- LiteSpeed servers with LSCache support
- Built-in CDN (fast worldwide delivery)
